LG Shows Off Wallpaper Display Under 1mm Thick

The screen-making subsidiary of LG called LG Display, is dedicated to OLED panels and has developed an incredibly thin television. In LG Display's home country of South Korea, they held a press event on Tuesday, to show off a "wallpaper" proof-of-concept television. The 55-inch OLED (organic light-emitting diode) display weighs 1.9 kilograms and is less than a millimeter thick. The TV can also stick to the wall by using a magnetic mat that you can attach to your wall. When you want to remove the display, you peel the screen off the mat from the wall.

LG Display launching this screen was only part of the bigger picture of what their future holds. LG Display has said its display strategy will be based on OLED technology. The head of LG Display's OLED Business Unit Sang-Deog Yeo said in a press release "OLED represents a groundbreaking technology not only for the company but also for the industry."

Years ago, display technology was focused on tech like LCD (liquid crystal display) and plasma, but now, it's starting to lean more towards LED technology.

You very well might be seeing a lot of OLED in the future. LG Display believes OLED could be used in all display technology products in the future. The technology put an organic compound layer that allows its displays to not only be thin but also curved. The organic material also lets off its own light, so it doesn't need a backlight. This helps with making the screens so thin that OLED is also the ideal choice for a lot of wearables and other mobile products, not just TVs.

Companies like LG, Samsung and Sony have used some OLED screens, but the cost of display production is rather high. Some of that cost is because of production failures, meaning more waste increases the costs of the screens that actually make it through production. Then those costs are passed to consumers. For example, LG's 65-inch, 4K OLED TV costs $9,000.

LG also said at Tuesday's press event that it is making significant progress in developing OLEDs. The company is the first to mass-produce large-screen OLEDs for televisions and says its yield has hit 80%, still lower than LCDs. The issues with yield as well as the price, may mean displays like the "wallpaper" display, won't be available at stores for a reasonable price in the near future.

Also on Tuesday, LG Display announced that they expect to sell 600,000 OLED TV panels this year and 1.5 million panels next year. The company also shared comments by a professor at the University of Rochester in New York and "the father of OLED" Ching W. Tang. He believes we won't be seeing a lot of OLED displays for another 5-10 years. He claims then that OLED could outpace LCDs altogether.

The "wallpaper" display seems like a pretty cool idea, but I can't imagine how much they will be charging for something like that. I'm still prepared to start seeing a lot more OLED products to come.
